The nominal minimum SWR set with the feedpoint matchbox is at 3.750 MHz. We can build the matchbox for any center frequency on the 80 meter band by request at the time an order is placed. Please contact us at vibroplex@vibroplex.com before placing an order to discuss this. There is no extra charge for this service, but may add a delay of a few days to build the antenna and ship the order.
